Positive indications – studies and publications


The chronic migraine study is currently being carried out at nine clinics in Germany and Finland. The study has been delayed due to Covid-19, but is expected to initiate treatment of the last patients during the first quarter of 2022.

The results from an interim analysis of the first 53 patients were presented in May, 2019. The external data monitoring committee recommended that the study should continue according to plan, and that the number of patients participating in the study should remain unchanged. We interpret this as a strong indication that the study is likely to achieve the desired result. As the CE-mark already is in place based on the interim analysis data, the study is now moving forward towards completion to become a support in product launch and sales activities - and also constitute a foundation to understand our enterprize value. 

Primary effect target: evaluate the effect of K.O.S. treatment through the decrease of the number of days/months with headaches with moderate to serious intensity.

Scope: <140 patients in nine clinics in Germany and Finland

Type: double-blind, randomized, placebo controlled

Inclusion: males/females in the 18-65 age bracket, migraine diagnosis <60 years of age, chronic migraine diagnosis< three months

Design: 50/50 randomized to active versus placebo treatment, 4 weeks screening, 6 weeks treatment, follow-up 4 weeks



A rhinitis study is currently being conducted in 13 clinics in six countries in the EU and the UK. An interim analysis that was performed during autumn 2020 showed that the statistical goals could not be achieved. Therefore patient recruitment was stopped. Follow-up of active patients will be conducted.

Primary effect target: evaluate the improvement effect of K.O.S. treatment on NAR (non-allergic rhinitis) with, among other things, Total Nasal Symptom Score (TNSS)

Scope: Around 300 patients in 13 clinics in six countries in the EU and the UK

Type: double-blind, randomized, placebo controlled

Inclusion: males/females in the 18-65 age bracket, rhinitis diagnosis >12 weeks, nasal congestion estimated at >2 (on a scale of 0-3)

Design: 50/50 randomized to active vs placebo treatment, 10 days screening, two treatments at four-week intervals, follow-ups with 12 weeks intervals for 12 months
